STEP 14: INSTALLING SIDE SHEET METAL PANELS:
IMPORTANT: If you will be installing 1/4” foil insulation on your building, go to pages 43 and 44 and read the
instructions for installing insulation. Insulation must be installed between the frame and the sheet metal panels.
SHEET METAL PANELS FOR THE SIDE OF THE BUILDING ARE 8’-1”, 10’-1”, OR 12’-1” LONG.
Start at one corner of the building. (It is preferred that you chose a corner that is away from the prevailing wind). Make
sure that the frame is plumb when installing the first side panel. All additional panels will depend on the first panel being
plumb and square.
Carefully place the first panel on the slab sheeting ledge (or at the bottom of the base rail if no sheeting ledge is avail-
able.) Place the overlap edge
at the starting corner of the building. NOTE: If the building is 40’ long, trim 4 1/2” off
the leading edge or starting edge of the panel. This is done to allow the corner trim to fit properly at the other
end of the building when the last panel is trimmed to fit. This will allow you to easily overlap the second panel over
the first and so on down the length of the building.
Attach the panels to the hat channels with #12 x 3/4” painted, Self-Drilling Screws with rubber washers. Place one screw
about 3/4” to one side of each major rib.
NOTE: It is important to keep the panels from stretching or compressing in width as you install them. The panels should
be 36” from the center of the major rib on one side of the panel to the center of the major rib at the other side of the
panel. Measure each panel as you go or pre-mark the building frame every 36” to check the panel width as you go.
The last panel installed on the side on the building should come out flush with the other end of the building frame if the
length is devisable by 3. If not (example 20’ or 25’ long building) you will need to trim the last panel to be flush with the
building frame. Be careful not to scratch up the bottom of the panels as you place and adjust them on the concrete slab
or sheeting ledge.
Tip: To keep the screws in a straight line down the length of the building, install screws next to the 1st major rib. Hold a
straight edge between the center point of the screw and the center of the hat channel at the other side of the panel and
mark dots along that line where the remaining screws will be located with a felt tip marker. You can also tie a small loop
in one end of a string, hook it over the first screw and draw the string to the center of the hat channel. Holding the string
taut, use a felt marker to mark location points for the remaining screws. A speed square and a pencil can also be used.
